Consumption,asset wealth,equity premium,term spread,and flight to quality

We link transitory deviations of consumption from its equilibrium relationship with aggregate wealth and labor income to equity returns on the one hand, and to two characteristics of bond investors—the premium demanded to hold long‐term assets, and “flight to quality” behavior—on the other hand. Using a panel of 10 euro area countries over the period 1984Q1–2017Q4, we show that a rise in the consumption–wealth ratio predicts both higher equity returns and the future term spread, while a fall in the consumption–wealth ratio explains a large fraction of the rise in the spread between the “risky” and the “safe‐haven” bond.     

Tick Size and Financial Reporting Quality in Small-Cap Firms: Evidence from a Natural Experiment

Using a natural experiment (the SEC's 2016 Tick Size Pilot Program), we investigate the effects of an increase in tick size on financial reporting quality. The tick size pilot program reduces algorithmic trading (AT) and increases fundamental investors’ information acquisition and trading activities. This in turn increases the scrutiny of managers’ financial reporting choices and reduces their incentives to engage in misreporting. Using a difference-in-differences research design, we find a significant decrease in the magnitude of discretionary accruals, a significant reduction in the likelihood of just meeting or beating analysts’ forecasts, and a marginally significant decrease in restatements for the treated firms in the pilot program. Furthermore, we find that the change in financial reporting quality is concentrated in treated firms experiencing decreases in AT and increases in information acquisition activities. We also find that the mispricing of accruals is significantly lower for treated firms. Taken together, our results suggest that an increase in tick size has a causal effect on firms’ financial reporting quality.     

Does the severity of a client’s negative environmental,social and governance reputation affect audit effort and audit quality?

In recent years, investors have begun to value companies’ reputations through their environmental, social, and governance (ESG) practices. ESG risk can affect business processes and controls and can heighten financial risk and threaten a firm’s survival. This study examines whether and how the severity of media coverage of a firm’s negative ESG issues (tainted ESG reputation) is associated with audit effort and audit quality. I find that auditors manage the higher expected engagement risk conveyed by tainted ESG reputation by applying higher audit effort. Next, I observe that the increased effort is associated with auditors likely detecting and requiring adjustments for material misstatements and that tainted ESG reputation is associated with fewer misstatements (i.e., reduces poor audit quality). The association between tainted ESG reputation and audit quality is driven primarily by increased audit report lag, not by increased audit fees. Further, I find that tainted ESG reputation is positively associated with audit effort and reduces poor audit quality for up to three years. The results also show that the audit effort and audit quality effect vary across the three components of ESG.     

Do seasoned industry specialists provide higher audit quality? A re-examination

The purpose of this paper is to re-examine the recent findings in Gaver and Utke (2019) (GU) who find that seasoned industry specialist auditors provide higher audit quality. We first illustrate how the magnitude of residuals from the accruals model can vary significantly by industry, thus highlighting the importance of including industry fixed effects when the dependent variable is discretionary accruals. We next replicate GU’s findings. We first attempt to replicate prior literature after including industry fixed effects in the audit quality (discretionary accruals) models. This is an important control, as the relevant benchmark for a firm with an industry specialist auditor is a peer firm in the same industry with a non-specialist auditor. We find that after including industry fixed effects, there is no association between seasoned industry specialist auditors and discretionary accruals. We also find that the association between industry specialization and discretionary accruals is very sensitive to the way in which the researcher calculates specialization. Our findings are informative for shareholders of public companies who vote on auditor ratification.     

Institutional quality,investment efficiency,and the choice of public–private partnerships

We examine a sample of 625 public–private partnership (PPP) firms from 1980 to 2015 that straddle nine countries with varying degrees of economic development and PPP markets. We find that the motivations of the firms that undertake PPP investments vary. While private sector firms in economies with low institutional quality choose to engage in PPPs to alleviate capital constraints attributed to underinvestment, those in economies with high institutional quality participate in PPPs to solve the problem of overinvestment due to an abundant cash flow. In the long run, the benefits of lower capital constraints through PPP investments are more pronounced in economies with high institutional quality.     

绿色海洋GDP核算实例研究

在海洋强国战略视域下，以高质量发展为主题，综合海洋资源、环境、生态和社会等因素，选取辽宁省作为研究区域进行海洋 GDP核算实例研究，将资源损耗价值、环境污染损失、生态效益价值、社会牺牲成本纳入绿色海洋 GDP核算中。通过阐述绿色海洋 GDP核算的内涵和方法，分析绿色核算在海洋经济核算中实施的可行性，对前期绿色海洋 GDP核算指标进行修正，并提出开展绿色海洋 GDP核算的保障措施，力求对转变海洋经济发展方式、加快实现海洋经济高质量发展做出有益贡献。     

税收执法提升了企业财务报告质量吗——基于“金税工程三期”的准自然实验

以2011~2018年中国A股上市公司为样本，以税务稽查系统改革"金税工程三期"为准自然实验，探讨税收执法的公司治理效应，采用双重差分模型，实证检验了金税工程三期改革对企业财务报告质量的影响。研究发现：金税工程三期改革显著提升了企业财务报告质量。金税工程三期改革的公司治理效应在治理环境较弱、信息透明度更低、融资需求更高的公司表现得更为显著。从作用机制来看，金税工程三期改革显著增强了税收执法力度，减少了企业的避税行为。     

政府质量、科技创新与绿色GDP——中国省际空间溢出效应及区域差异对比

通过构建嵌入政府质量和科技创新因素的经济增长模型，利用中国30个省份2004~2017年的平衡面板数据，实证检验政府质量、科技创新对绿色GDP发展的影响。研究发现：中国绿色GDP存在显著的空间集聚性及明显的区域差异性。在经济权重矩阵影响下，不同地区的政府效率、市场化程度、公平程度和腐败程度对绿色GDP的影响不同，其中政府效率、公平程度能有效促进经济发展较好地区的绿色GDP增长，却会抑制比较落后地区绿色GDP的增长；市场化程度对大部分地区绿色GDP呈现促进作用；腐败程度对地区绿色GDP增长呈阻碍作用。科技创新对各地区绿色GDP均起到积极的促进作用。因此，提升绿色GDP发展水平不仅需要提高地方政府质量，为绿色GDP发展提供符合实际的政策指导意见，还需激活企业科技创新能力，为绿色GDP发展提供有力科技保障。     

信任式服务的顾客忠诚形成机制及实践启示

信任式服务因其专业性和（或）“纯服务”等鲜明特征而使之显著区别于其他类型的服务，其顾客忠诚形成机制也因此具有独特性。针对医疗服务的实证分析表明：在信任式服务中，顾客信任在顾客忠诚形成机制体中起着关键性的作用，形成“服务质量→顾客信任→感知价值→顾客满意→顾客忠诚”的逻辑链；服务互动质量和结果质量通过顾客信任对顾客感知价值和顾客满意产生影响，进而影响顾客忠诚，但服务环境质量对顾客信任和顾客忠诚没有显著影响。因此，对顾客形成机制的研究需要区分产品和服务的类型以及服务质量的类型。提供信任式服务的组织应该重视并加强对服务人员与顾客互动能力的培养，提升服务人员与顾客的服务互动质量，并切实保障和提高服务结果质量，从而增强顾客信任，提升顾客忠诚。
